Resto Shaman pvp HELP!

hello everyone im just starting my resto pvp spec today and ive never played heals ever for pvp in my life, but i feel like shaman is my favorite compared to the other classes, but i need some help with what the hell im suppose to do with macros and what totems im suppose to be using,

Use your brain, its simple. I started shaman for 3 months ago, and im already playing at 2.2k. You dont even have to ask for tricks or tips, figure them out yourself that is the best way to understand a class.
